Key legal question
Whether the maintenance contribution for son T. was fixed in a willfully incorrect way regarding possible future education allowances.
Extracted holding
The challenge failed because the appellant did not show that the appellate court's wording was arbitrary; the result was not untenable even if future educational allowances could later affect the amount.
Extracted reasoning
The federal court held that no clear contradiction existed between the reasons and the dispositive part, that possible future changes did not make the decision arbitrary, and that the appellant merely argued the consequences without meeting the strict burden of alleging arbitrariness.
